A Korean research team found a method to inhibit the fouling of membranes, which are used in the desalination process that removes salt and dissolved substances from seawater to obtain drinking, domestic, and industrial water.
Molecules are some of life's most basic building blocks. When they work together in the right way, they become molecular machines that can solve
the most amazing tasks. They are essential for all organisms by, for example, maintaining a wide range of cellular functions and mechanisms.
What if you could create and control an artificial molecular machine? And make it perform tasks that serve us humans?
Many researchers are looking for ways to create and control such molecular machines, and research is going on in labs all over the world.
In a comprehensive ecological study, a team of scientists at the Max Planck Institute for Chemical Ecology in Jena examined three different species of the genus Drosophila and their interactions with their natural food resources, in particular the yeasts associated with these substrates. They found that vinegar flies do not necessarily prefer yeasts they know from their natural environments, but were also attracted by yeasts found in a foreign habitat.
Singaporeans suffering from sleep disorders may have help from mechanism regulating biological clock
Biological clocks are an organism's innate timing device. It is composed of specific proteins called clock proteins, which interact in cells throughout the body. Biological clocks produce and regulate circadian rhythms - the physical, mental, and behavioural changes that follow a daily cycle.
The Video Enabled Justice (VEJ) Independent Evaluation was led by academics from the University of Surrey's Department of Sociology and the Centre for Translation Studies in the School of Literature and Languages. Sponsored by the Sussex Police and Crime Commissioner Katy Bourne, the report investigated the impact of a new booking tool used in the organisation of first appearance remand hearings in video court.
Here's a new chapter in the story of the miniaturisation of machines: researchers in a laboratory in Singapore have shown that a single atom can function as either an engine or a fridge. Such a device could be engineered into future computers and fuel cells to control energy flows.
RICHLAND, Wash. -- Software vulnerabilities are more likely to be discussed on social media before they're revealed on a government reporting site, a practice that could pose a national security threat, according to computer scientists at the U.S. Department of Energy's Pacific Northwest National Laboratory.
Koalas are one of the world's most charismatic animals. But there is a lot we still don't know about them. For example, how do the marsupials access water in the treetops? Do they only absorb moisture from the gum leaves they eat? Or do they come down from the trees to drink from a waterhole? Until now, no one really knew.
Researchers from University of Pennsylvania published a new paper in the Journal of Marketing that explains that the device people use to communicate can affect the extent to which they are willing to disclose intimate or personal information about themselves.
The study forthcoming in the Journal of Marketing is titled "Full Disclosure: How Smartphones Enhance Consumer Self-disclosure" and is authored by Shiri Melumad and Robert Meyer.
WOODS HOLE, Mass. --The COVID-19 pandemic is a stark reminder that we move through a world shaped by unseen life. Bacteria, viruses, and other microscopic organisms regulate the Earth's vital functions and resources, from the air we breathe to all our food and most of our energy sources. An estimated one-third of the Earth's microbes are literally hidden, buried in sediments deep below the ocean floor. Now, scientists have shown that these "deep biosphere" microbes aren't staying put but are bubbling up to the ocean floor along with fluids from buried petroleum reservoirs.
Army researchers predict quantum computer circuits that will no longer need extremely cold temperatures to function could become a reality after about a decade.
For years, solid-state quantum technology that operates at room temperature seemed remote. While the application of transparent crystals with optical nonlinearities had emerged as the most likely route to this milestone, the plausibility of such a system always remained in question.
Mars had a global magnetic field much earlier--and much later--in the planet's history than scientists have previously known.
A planet's global magnetic field arises from what scientists call a dynamo: a flow of molten metal within the planet's core that produces an electrical current. On Earth, the dynamo is what makes compass needles point north. But Mars' dynamo has been extinct for billions of years.
A group of researchers from University of Toronto Engineering and SickKids Hospital have developed a new way to deliver molecules that target specific genes within cells. Their platform, which uses a modified form of diptheria toxin, has been shown to downregulate critical genes in cancer cells, and could be used for other genetic diseases as well.
The team, led by professors Molly Shoichet and Roman Melnyk of SickKids Hospital, found inspiration from an unexpected source: diphtheria toxin.

1. Investing in Our First Line of Defense: Environmental Services Workers
A new USC study suggests that temporarily suppressing the body's immune system during the early stages of COVID-19 could help a patient avoid severe symptoms.
That's because the research, just published online in the Journal of Medical Virology, shows that an interaction between the body's two main lines of defense may be causing the immune system to go into overdrive in some patients.
